What I do

I receive a filename with the line numbers that are not covered by a test

• Analyse the code at the uncovered lines for the file in the current project
• Generate one detailed plan to add tests to cover the gaps for each file

How I do it

Step 1: Read the code in the actual file for the uncovered lines Step 2: Write a detailed plan to develop test scenarios that would cover the missing lines for the target file Step 3: Report the plan with the test file to add/edit, the detailed scenario and branches that will be covered, the helpers that will be reused and the mocks to produce when applicable

When producing test scenarios plan:

• Favor contracted collaborator tests + thin integration tests
• Write tests that hit actual code implementation for a wider branch activation
• Build mocks/stubs using Mox when there's a need to predictably simulate an external API call
• Re-use helpers, mocks and stubs when they already exists
• DO NOT leak test concerns into implementation code

When to use me

Run when a file name with a list of line numbers for uncovered lines is provided
